[SCSI] libiscsi: Added new boot entries in the session sysfs

2013-06-27T01:04:11Z

This is the kernel part of the modification to extract the net params from the ibft sysfs to the iface struct used for the connection request upon sync_session in the open-iscsi util. Three new session sysfs params are defined: boot_root - holds the name of the /sys/firmware/ibft or iscsi_rootN boot_nic - holds the ethernetN name boot_target - holds the targetN name Signed-off-by: Eddie Wai Reviewed-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] Workaround for disks that report bad optimal transfer length

2013-06-24T20:00:10Z

Not all disks fill out the VPD pages correctly. Add a blacklist flag that allows us ignore the SBC-3 VPD pages for a given device. The BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages scsi_device parameter to bypass VPD scanning. Also blacklist the offending Seagate drive model.

[SCSI] Allow error handling timeout to be specified

2013-06-04T18:16:24Z

Introduce eh_timeout which can be used for error handling purposes. This was previously hardcoded to 10 seconds in the SCSI error handling code. However, for some fast-fail scenarios it is necessary to be able to tune this as it can take several iterations (bus device, target, bus, controller) before we give up. Signed-off-by: Martin K.

[SCSI] libsas: implement > 16 byte CDB support

2013-06-04T18:15:59Z

Remove the arbitrary expectation in libsas that all SCSI commands are 16 bytes or less. Instead do all copies via cmd->cmd_len (and use a pointer to this in the libsas task instead of a copy). Note that this still doesn't enable > 16 byte CDB support in the underlying drivers because their internal format has to be fixed and the wire format of > 16 byte CDBs according to the SAS spec is different. the libsas drivers (isci, aic94xx, mvsas and pm8xxx are all updated for this change.

[SCSI] iscsi class, qla4xxx: fix sess/conn refcounting when find fns are used

2013-05-10T14:47:53Z

This fixes a bug where the iscsi class/driver did not do a put_device when a sess/conn device was found. This also simplifies the interface by not having to pass in some arguments that were duplicated and did not need to be exported.

[SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_type

2013-05-10T14:47:52Z

These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them. The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix. Signed-off-by: James Bottomley

[SCSI] sd: use REQ_PM in sd's runtime suspend operation

2013-05-06T19:48:17Z

With the introduction of REQ_PM, modify sd's runtime suspend operation functions to use that flag so that the operations to put the device into runtime suspended state(i.e. sync cache and stop device) will not affect its runtime PM status.

[SCSI] libosd: remover duplicate __bitwise annotation

2013-05-02T19:15:10Z

__be32 is already a __bitwise type so we don't need the second __bitwise here. It causes a Sparse error: include/scsi/osd_protocol.h:110:26: error: invalid modifier Signed-off-by: Dan Carpenter Acked-by: Benny Halevy Signed-off-by: James Bottomley
